Title: Improvements in means for loading and packing refuse in vehicles
IPC: B65F3/18
Filed: 1945-07-23
Abstract: 596,169. Loading and packing refuse vehicles. SHERWOOD, J., ALLCHURCH, S., and SHEFFLEX, Ltd. July 23, 1945, No. 18846. [Classes 78(iii) and 78(iv)] Means for loading and packing refuse into a refuse collecting vehicle comprise a substantially closed chamber 2 at the rear of the vehicle, in which is a . container 4 for receiving the contents of. dustbins, the container being rotatable on trunnions 5 carried by a cradle 6 guided on inclined tracks 7 so that it may be raised and tipped to discharge its contents into the main body 1 of the vehicle. The refuse is compacted by a rake 8 on arms 9 hinged at 10 to brackets 11 secured to a trolley 12 running on rails 13 and operated by the piston rods 25 of a pair of hydraulic rams 24, the rake being guided by rollers 14 cooperating with fixed guides 15, 16, 21 and a pivoted spring-biassed guide 17 so that it shifts refuse on its forward but not on its rearward stroke. Alternatively the rake 8 and guides 15, 16, 17, 21 may be replaced by a flap hinged to be inoperative in the rearward direction of travel. The trolley 12 is connected to the cradle 6 by wire ropes or roller chains 22 passing over pulleys or sprockets 23 so that the trolley makes a complete forward and rearward stroke for each raising and lowering of the cradle. The connection between the cradle and the trolley may be modified to provide a velocity ratio other than unity. Two toothed pinions 26 fast on a shaft 27 journalled on the trolley engage with toothed racks 28 on the lower side of the rails 13 to prevent the trolley turning askew. The tilting of the container 4 at the top of its travel is effected by the engagement of cam surfaces 29 on the container engaging rollers 30. The rear chamber 2 is hinged at 3 to the rear of the vehicle body so that it swings clear when the latter is tilted to discharge the refuse.
Patent GB-887911-A (GB)
Title: Improvements in methods and apparatus for moulding plastic materials
Inventor: POLLARD HAROLD JOHN
IPC: B29D22/00
Filed: 1957-06-17
Abstract: 887,911. Moulding panels. BRISTOL AEROPLANE PLASTICS Ltd. July 14, 1958 [June 17, 1957], No. 19039/57. Class 87(2). Panels are moulded from fibrous reinforcing material, e.g. glass fibre, and a settable liquid impregnant, e.g. polyester resin, by enclosing the fibrous material in the space 11 between an elastic membrane 2 and a rigid non-porous mould 3, filling the space 11 with the settable liquid, subjecting the membrane 2 to fluid pressure to move it towards the rigid mould 3, the fluid being confined against the side of the membrane opposite to the rigid mould 3 by a rigid backing member 1, and the liquid made to set while the pressure is maintained on the membrane. The fibrous material is first placed over the membrane 2 and the mould 3 then moved into position, co-operating knives 5, 6 serving to trim any excess material. The liquid is introduced through pipe 12 until the mould space 11 is filled and liquid begins to issue from pipe 13, compressed air then being admitted through pipe 9 to the peripheral groove 10 in the backing member 1 so that, starting at its periphery, the fibrous layer is moved outwardly into contact with mould 3 and impregnated with the liquid, excess liquid escaping through pipe 13. The curing of the liquid impregnant, when a thermosetting resin, may be effected by circulating hot fluid between the groove 10 and an outlet pipe at the centre of the backing member. With thermoplastic resins, the impregnant will be supplied in a hot liquid state into a heated mould and the mould then cooled. In an alternative method of working, after filling the mould space 11 with liquid impregnant and allowing air to escape through pipe 13, the pipe 13 is closed so that upon inflation of the membrane 2 excess liquid is driven back through the pipe 12. In this case it is desirable that the inflation pipe 9 should lead into a recess on the surface of the backing member 1 near its centre so that compression of the fibrous material takes place progressively from the centre outwards.

Title: Arrangements for detecting, measuring or directly using for control purposes, the derivatives (speed, acceleration, change of acceleration and higher derivatives) of motion
IPC: G01P15/00
Filed: 1945-07-26
Abstract: 604,598. Measuring speed, acceleration, &c. OSTER, L. E. W. MONTROSE-, and POLLOPAS PATENTS, Ltd. July 26, 1945, No. 19139. [Class 106 (iii)] An arrangement for detecting, measuring, or using for control purposes, the derivatives (speed, acceleration, and higher derivatives) of motion, comprises one or more groups each consisting of a combination of two differential gears. One of the three movable parts of each differential drives a speed responsive device, a second part is rotated at constant speed, and the third is subject to the motion to be analysed. A constant-speed motor 1 drives a governor through a differential gear 3, 4, 5 and motion applied to the cage 6 of the differential causes the runner 9 of the governor to rise and fall according to the speed and direction of rotation of the applied motion. In order to balance the system, a second differential is rotated in an opposite sense through gears 10, 20, the part 3 of the second differential being driven in the same direction as the motor through an idler gear. Thus, the weights and the runner 19 of the second governor move in an opposite sense relative to those of the first governor, and, if connected to drive the cage 26 of a further differential in a second, similar group, the movements of the runners 29, 39 of the second group will give an indication of the second derivative of motion, i.e. acceleration. Further groups may be driven in a similar manner, " in cascade," to give the higher derivatives.

Title: Improvements in or relating to hank dyeing and like machines
IPC: D06B3/08
Filed: 1923-07-26
Abstract: 201,565. Schlumpf, J. July 31, 1922, [Convention date]. Operating clutches.-In a device for automatically advancing and simultaneously rotating in alternate directions the yarn rollers of dyeing machines around a vertical central axis, two toothed wheels driven in opposite directions are provided by means of which the drive-shaft of the yarn rollers may be driven in either direction, and one of the wheel drives, step by step, a rotary frame which carries the bearings for the rollers. The spur-wheels 5, 6 driven in opposite directions from the shaft 1 by means of bevel wheels 2, 3, gear with toothed wheels 7, 8 mounted on the shaft 9. The clutch 13 engaging with either of the clutch-faces 11, 12 enables the shaft 9 to be driven in either direction. The wheel 7 is provided with a second clutoh-face 16 with which a clutch-face 17 tends to engage under the action of a spring 19. This engagement drives the wheel 18 which is axially movable on the shaft 9 and gears with a spur-wheel 20 loosely mounted on the shaft 4 and provided with a projection 21 which engages a groove 22 on a ratchet-wheel 23. The wheel 20 also rotates by way of pinion 40 and toothed wheel 41, a cam-drum 42, in a groove 43 on which a pin 44 on the operating lever 45 engages. the lever 45 having also a pin 46 which actuates the clutchface 13. The ratchet-wheel 23 is provided with a guide-rib 26 engaging an annular groove 27 in the spur-wheel 18, which may thus be held out of contact with the clutch-face 16 against the action of the spring 19. The ratchet-wheel 23 cooperates with a pawl 28 hinged to an operating lever 29 which is moved by a controlling cam 32 against the action of a spring 34. The cam 32 is rigidly connected to the wheel 7. An adjustable spindle 37 enables the movement of the operating lever 29 to be varied. In operation, rotation of the shaft 1 causes rotation of wheel 7 and cam 32 which feeds the ratchet-wheel 23 forwardly. When the ratchet-wheel has completed half a revolution, the guide-rib 26 releases wheel 18 which, under the action of spring 19, engages with wheel 7 by way of the clutch-faces 16, 17. The wheel 18 then rotates wheel 20 which drives the ratchet-wheel so that the guide-rib 26 re-engages with groove 27 and moves wheel 18 out of contact with wheel 7. The step-by-step movement thus imparted to wheel 20 is suitably transmitted to the rotary frame carrying the yarn rollers, the frame being moved around a central vertical sleeve. The pinion 40, wheel 41, and cam-drum 42 are always rotated through 180‹, so that the operating lever 45 causes the clutch-face 13 to engage alternately with the clutch-faces 11, 12. This causes the shaft 9 to rotate alternately in opposite directions, and these movements are transmitted by gearing co-operating with the wheel 55 to the yarn rollers.

Abstract: 1,272,681. Valves. A. AZIZ. 19 May, 1970 [17 April, 1969], No. 19687/69. Heading F2V. Control of fluid flow between valve passages 19, 20, 23, 24 is effected in response to the temperature of the fluid flow within bore 11 and by means of a wax-filled capsule 25 upon which a cylindrical valving member 30 is carried, the valving member being urged against a flared portion 27 of the capsule by means of a spring 35, having a plurality of ports 32 formed therein and carrying an annular sealing ring 33. In operation, a rise in temperature of the fluid causes the capsule to be displaced to the right, as seen in the Figure, such that the apertures become progressively obstructed and finally closed when the sealing ring 33 engages a shoulder 13 of the bore 11. In a modification (Fig. 2, not shown), the free end of the capsule acts as a valving member which co-operates either with the narrow bore 12 or with a sealing ring located against the shoulder 13. In further modifications, not shown, one of the valve passages may be blanked off. The valve is said to be usable with a vehicle engine lubricating system incorporating a lubricant heating or cooling apparatus.
